This patch I posted last fall: https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00711.html
still has not been reviewed, in spite of me pinging it several times before GCC 5 went into stage 4. Now that we're back in stage 1 again, can somebody please take a look at it? I've just re-tested it on mainline head.
FAOD, NVIDIA assigned the copyright on their original version of the patch to Mentor Graphics so there should not be any legal issue with it.
